Oh dear, don't want to get into the perennial discussion of handling vs. roadholding, veering off into the differences between grip and adhesion and a zillion other subtleties. Enough on the Web about that already. http://en.wikipedia.org/wiki/Automobile_handling
Don, by every account the Miata is a superb-handling vehicle, with the differences amongst the MX-5's NA, NB, and NC extensively discussed elsewhere... I don't want to go there. Besides, I'm old-school, with my frame of reference being my own first car which was an Austin Healey 3000.
My bad, as perhaps I should have prefaced my remark by saying that we're simply talking about a tall econobox.
I recognize the necessity for Low Rolling Resistance (LRR) tires and accept the roadholding degradation that comes with them. Mitsubishi's use of unequal tire sizes is interesting, both by keeping the Rolling Resistance lower with the skinny front tires as well as their effect on handling, specifically understeer IIUC. They went to a lot of trouble to incorporate these very unique tires on our iMiEV.
Don, as you've pointed out in the past, the iMiEV's roadholding (and perhaps overall handling) could be altered and undoubtedly improved with different tires. That's been done successfully on the Gen1 Honda Insight, but I continue driving on the original LRR tires as efficiency is my priority with that particular car, just as it is with the iMiEV.
For myself, I had very low expectations of the iMiEV in either handling or roadholding. That's not what I bought it for, as its controllable electric drivetrain coupled with its wonderfully functional overall package were the deciding factors.
What I've been very pleasantly surprised by is the iMiEV's overall handling relative to my initial expectations
. ZAPPED explained it nicely in his original posting on this thread.
Besides, not my area of expertise. 'Nuff said.
